sKIDLEss TIREy A Application filed J'une 14,

This invention relates to new and useful improvements in non-skid tires.

The invention has for an object the provision of a device of the classmentioned 5 which is of simple durable construction, de-

pendable in use and efficient in act-ion, and which can be manufacturedand sold at a reasonable cost.

The invention proposes the use of a plul rality of metal tractionmembers embedded in the shoe of a tire so that the outer fac-es are iushwith the tread,`and the traction members to bevarranged in groups andsecurely held against possible flying out while the l tire is on a wheelof a vehicle traveling at high speed. Each. traction member should havea shank and a head of any design, the shank to beconnected with chainsconstituting the holding means. Further, the traction mem- 29 bers maybe arranged with adjustable portions for resetting the outer face'sflushwith the tready after some wear. y

kF or further comprehension of theinvention, and of the objects andadvantagesthereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel featuresv of the invention are more particularly setforth. I In the accompanying drawingforming a material part of thisdisclosure Fig. 1 is a side elevational view of a wheel with a tireconstructed according to this invention.

ing in the direction of the arrows 7 7 of Fig'. 6. n Fig. 8 is a similarView to Fig. 3 but show-l mg another modified form.

The reference numeral v10 indicates gen' erally a wheel of'any design orconstruction provided with a tire 11 having a shoe 12. A

plurality of metaljtraction members.l 13 yare arranged in the tread ofthe tire land embedded so that their top faces are Hush with thetread.These metal traction members may be of various shapes and designs.

Each of the traction members 13 consists of a head portion 14: V,and ashank 15. The Shanks are connected with circular chains 16. Thesecircular chains, preferably three in number, extend completely aroundwithin the tire shoe and are also embedded in the material forming theshoe.' In'each of the circular chains 16, the metal tractionymembers arearranged in groups of two. This is readily seen in Fig. 1 in 'whichnumeral 17' indicates one group of two traction members, numeral 18 aspace, and numeral 17 another group of traction members and so oncoinpletely around the wheel. The circular chains 16 are connected bytransverse chains 1.9. These chains extend between metal tractionmembers of each of the circular chains.

In Figs. 1 to l inclusive, the metal traction members havey been sho-wnprovided with plain oval shaped heads.' JIn Figs. 5 and 6, the tractionmembers are shown formed with oval shaped headslahaving teeth. Theseteeth add to the traction ability of the meme bers. In the event thatany of the metal traction members become loose during use of the tire,the chains are 'depended upon to hold them against'fiying out vdue tocentrifugal force while a vehicle provided with the tires is inv motion.

In use, the metal tract-ion members, may

wear fasterthan the adjacent rubber portions of the tire shoe in thatthe rubber portions have a certain amount of give whichv tends vtoreduce wear. For this 'reason a modified form of traction member isillustrated in Fig.

7 which is provided with an adjustable head capable of being reset sothat its outer face isY ush with the tread of tire- Each 0f these' f 'YY' 1,759,590

traction members consists of a'shanlr casing V20I1provided with acentral'bore V271. VThe 'chains 16 and 19 are Connected with the cas`ing 20. A stem 22 is slidably mounted in the central bore 2l and isformed ,at its outer end with the traction head ll A screw 23 threadedlyengages thruthe stem 22 and is rotatively'hmolintedinthev shank casing20. This screw is provided with -a head 24 arranged for engagement by aturning tool. .Rotation of this screw moves the Vtraction Vhead andstein so that the face may be made flush with the tread. Y j

VIn Fig. 8, shank l5 is shown Ywith a plurality of upwardly projectingmembers 15a lembedded in the. tire 11 soas to keep the end f faces ofthe upwardly projecting members l5a flush with the outer periphery ofthe tire.
